A large ship requires a large number of various specifications of profiles, and the cutting port form and cutting precision have strict requirements. Since the ship body is a complex double curvature space curved surface structure, the profile supporting the ship body needs to be accurately cut into a non-right angle end shape to ensure its close fit with the ship body outer plate or other structural members; at the same time, the cutting precision of each type of profile will directly affect the quality and efficiency of the segmented assembly. Small cutting errors will be infinitely magnified when the segments are closed, resulting in assembly difficulties, excessive gaps, stress concentration and other problems, affecting the structural strength and watertightness of the ship body. The shipbuilding cycle is long and the cost is high, so the construction efficiency is very important. Profile cutting as a front-end process directly affects the progress of subsequent assembly, welding and other links.

[0050] Example 3 In this embodiment, a cutting positioning method for a cutting house of a profile is described, which includes the following steps: a.
